A fogging device (26) for introducing water and/or vapor into an intake air flow (10, 27) of a gas turbine (1-3 ) includes a sound-absorbing device (31, 35). This device may in particular be designed in the form of Venturi tubes (31), the water (29) being fed to the air flow (27) via nozzles ( 33) arranged at the narrowest location. In this way, the spraying of water for increasing the power output or for generally regulating the gas turbine can at the same time be combined with a silencer, and this in a comparatively simple construction.

What is claimed as new and desired to be secured by Letters Patent of the United States is: 1. A fogging device for introducing water, vapour, or both, into an intake air flow of a gas turbine, the fogging device comprising: sound-absorbing means including a plurality of tubular elements arranged essentially parallel to the direction of flow of the intake air flow; wherein each tubular element includes an interior space; and nozzles configured and arranged to introduce water, vapour, or both, into the intake air flow, the nozzles being arranged on the inside of the tubular elements and oriented for spraying water into the interior space. 2. The fogging device as claimed in claim 1, further comprising cavities between the tubular elements configured and arranged to be sound-absorbing. 3. The fogging device as claimed in claim 1, wherein the tubular elements each have a diameter that changes along their length. 4. The fogging device as claimed in claim 3, wherein the tubular elements each comprise a constriction in a middle region. 5. The fogging device as claimed in claim 4, wherein each tubular element includes an inlet side and an outlet side, and wherein the constriction is configured and arranged so that the elements have essentially the same diameter on the inlet side and on the outlet side and have a diameter smaller by 20 to 30% in the middle region. 6. The fogging device as claimed claim 1, wherein the tubular elements each have a diameter that changes along their length and includes a constriction in a middle section, and wherein the nozzles are arranged in the region of the constriction. 7. The fogging device as claimed in claim 6, wherein each element includes an inlet side and an outlet side, and wherein the constriction is configured and arranged so that the elements have essentiall the same diameter on the inlet side and on the outlet side and have a diameter smaller by 20 to 30% in the middle region. 8. The fogging device as claimed in claim 1, further comprising: means for spraying water having a droplet size within the range of 10 to 50 μm into the intake air flow, said means comprising said nozzles. 9. A method of increasing or regulating the power output of a gas turbine comprising: providing said gas turbine with a fogging device as claimed in claim 1; and operating said fogging device to increase or regulate the power output of said gas turbine. 10. The method as claimed in claim 9, further comprising: spraying water with the fogging device into the intake air flow essentially directly upstream of a first compressor stage, of a second compressor stage, or both, and optionally downstream of a further fogging device. 11. The fogging device as claimed in claim 1, further comprising: at least two nozzles circumferentially distributed for each tubular element. 12. A fogging device for introducing water, vapour, or both, into an intake air flow of a gas turbine, the fogging device comprising: sound-absorbing means including a plurality of tubular elements arranged essentially parallel to the direction of flow of the intake air flow; and at least two supporting walls arranged essentiall perpendicularly to the direction of flow of the intake air flow, between which at least two supporting walls the water, vapour, or both is to be fed and into which at least two supporting walls the tubular elements are admitted so that the tubular elements pass through the at least two supporting walls.
